Gassco announces succesful removal of North Sea platform

KOPERVIK -- The H7 compressor installation in the German sector of the North Sea has been removed as planned.

This platform stood on Norpipe and came on line in 1977. Its compressors were used to maintain pressure in the pipeline, which carries gas from Norway’s Ekofisk area to the Norsea Gas Terminal at Emden in Germany.

The compressors were shut down in 1999, but the installation remained operational until 2007. It was then disconnected from Norpipe and shut down, with all personnel removed.

Statoil has been responsible for the removal project on behalf of H7 operator Gassco, while AF Decom Offshore AS has served as the removal and disposal contractor.

Key sub-contractors are Swire Blue Ocean, which provided the jack-up vessels used for the removal, and Deep Ocean as the company responsible for the project’s subsea operations.

A final decision to remove the platform was taken in October 2010. Remaining work is limited, with clearing of the seabed and some gravel deposition on the site due to be done in September.
